Abstract

This study evaluated the efficacy, mineral content and biocompatibility of bleaching gels with low concentrations of hydrogen peroxide (PH; H2O2) containing hyaluronic acid (HA) or carbomer 940 (CAR), NF_TiO2 nanoparticles (NPs) and irradiated with Violet LED. Sound bovine enamel samples were treated with (n=10): HA-1.5%HP, HA-6%HP, CAR-1.5%HP, CAR-6%HP, HA-1.5%HP+LED, HA-6%HP+LED, CAR-1.5%HP+LED, CAR-6%HP+LED, or 35%HP-commercial. The protocol was performed in 3 sessions of 30 minutes with a 7-day interval between sessions... Abstract is available with the full The electronic document (AU)
